Answer:

Median

Step-by-step explanation:

Since, after correction also salary is the lowest salary than any other salary, this means outlier is present in data and it affects the data so much. Thus we use the Median here.

Mean, Median and Mode are used to measure Central tendency.

Mean is the average of all observation. It is mainly used the data is normally distributed and it has no outlier.

Minimum: It can be found by arranging the data in ascending order, the first value we will get is the minimum value.

The middle observation of given data is called Median. It is used when an outlier is present in the data.

The mode is the observation which has a high number of repetitions (frequency).

The median (half-above and half-below) could not have changed, because "corrected value was still lower than any other salary" does not change the position of that observation (still least) in the sorted list of salaries.

Answer:

Step-by-step explanation:

Here is the correct and complete question: The units digit of a two-digit number is twice the tens digit. If the digits are reversed, the new number is 9 less than twice the original number. What is the original number?

Lets assume the original number be"10y+x". (x is unit digit and y is 10th digit)

∴ if number is reversed then resulting number be "10x+y".

As given: x= 2y

and $10x+y= 2(10y+x)-9$
